Problem: A breastfeeding client asks the nurse, "Why has my baby lost 5 ounces since she was born?" What is the best response by the nurse? "She may lose weight until your milk comes in." "It is normal for the baby to lose 5% to 10% of her weight during the first week due to diuresis." "The baby may be dehydrated, which is not uncommon in a breastfed baby." "The baby is having bowel movements, which results in a weight change."
